Copyright © 2009 Pearson Prentice Hall. All rights reserved An Overview of the Cost of Capital The cost of capital acts as a link between the firm’s long-term investment decisions and the wealth of the owners as determined by investors in the marketplace. It is the “magic number” that is used to decide whether a proposed investment will increase or decrease the firm’s stock price. Formally, the cost of capital is the rate of return that a firm must earn on the projects in which it invests to maintain the market value of its stock.

Copyright © 2009 Pearson Prentice Hall. All rights reserved Some Key Assumptions Business Risk—the risk to the firm of being unable to cover operating costs—is assumed to be unchanged. This means that the acceptance of a given project does not affect the firm’s ability to meet operating costs. Financial Risk—the risk to the firm of being unable to cover required financial obligations—is assumed to be unchanged. This means that the projects are financed in such a way that the firm’s ability to meet financing costs is unchanged. After-tax costs are considered relevant—the cost of capital is measured on an after-tax basis.
Copyright © 2009 Pearson Prentice Hall. All rights reserved Assume the ABC company has the following investment opportunity: - Initial Investment = $100,000 - Useful Life = 20 years - IRR = 7% - Least cost source of financing, Debt = 6% Given the above information, a firm’s financial manger would be inclined to accept and undertake the investment. The Basic Concept Why do we need to determine a company’s overall “weighted average cost of capital?”
Copyright © 2009 Pearson Prentice Hall. All rights reserved Imagine now that only one week later, the firm has another available investment opportunity - Initial Investment = $100,000 - Useful Life = 20 years - IRR = 12% - Least cost source of financing, Equity = 14% Given the above information, the firm would reject this second, yet clearly more desirable investment opportunity. The Basic Concept (cont.) Why do we need to determine a company’s overall “weighted average cost of capital?”
Copyright © 2009 Pearson Prentice Hall. All rights reserved The Basic Concept (cont.) Why do we need to determine a company’s overall “weighted average cost of capital?” As the above simple example clearly illustrates, using this piecemeal approach to evaluate investment opportunities is clearly not in the best interest of the firm’s shareholders. Over the long haul, the firm must undertake investments that maximize firm value. This can only be achieved if it undertakes projects that provide returns in excess of the firm’s overall weighted average cost of financing (or WACC).
Copyright © 2009 Pearson Prentice Hall. All rights reserved Specific Sources of Capital: The Cost of Long-Term Debt The pretax cost of debt is equal to the the yield-to-maturity on the firm’s debt adjusted for flotation costs. Recall that a bond’s yield-to-maturity depends upon a number of factors including the bond’s coupon rate, maturity date, par value, current market conditions, and selling price. After obtaining the bond’s yield, a simple adjustment must be made to account for the fact that interest is a tax-deductible expense. This will have the effect of reducing the cost of debt.
Copyright © 2009 Pearson Prentice Hall. All rights reserved Duchess Corporation, a major hardware manufacturer, is contemplating selling $10 million worth of 20-year, 9% coupon bonds with a par value of $1,000. Because current market interest rates are greater than 9%, the firm must sell the bonds at $980. Flotation costs are 2% or $20. The net proceeds to the firm for each bond is therefore $960 ($980 - $20). Net Proceeds Specific Sources of Capital: The Cost of Long-Term Debt (cont.)

Copyright © 2009 Pearson Prentice Hall. All rights reserved Duchess Corporation is contemplating the issuance of a 10% preferred stock that is expected to sell for its $87-per share value. The cost of issuing and selling the stock is expected to be $5 per share. The dividend is $8.70 (10% x $87). The net proceeds price (N p ) is $82 ($87 - $5). r P = D P /N p = $8.70/$82 = 10.6% Specific Sources of Capital: The Cost of Preferred Stock
Copyright © 2009 Pearson Prentice Hall. All rights reserved Specific Sources of Capital: The Cost of Common Stock There are two forms of common stock financing: retained earnings and new issues of common stock. In addition, there are two different ways to estimate the cost of common equity: any form of the dividend valuation model, and the capital asset pricing model (CAPM). The dividend valuation models are based on the premise that the value of a share of stock is based on the present value of all future dividends.

Copyright © 2009 Pearson Prentice Hall. All rights reserved WACC = r a = w i r i + w p r p + w s r r or n The weights in the above equation are intended to represent a specific financing mix (where w i = % of debt, w p = % of preferred, and w s = % of common). Specifically, these weights are the target percentages of debt and equity that will minimize the firm’s overall cost of raising funds. The Weighted Average Cost of Capital Capital Structure Weights
Copyright © 2009 Pearson Prentice Hall. All rights reserved WACC = r a = w i r i + w p r p + w s r r or n The Weighted Average Cost of Capital Capital Structure Weights One method uses book values from the firm’s balance sheet. For example, to estimate the weight for debt, simply divide the book value of the firm’s long-term debt by the book value of its total assets. To estimate the weight for equity, simply divide the total book value of equity by the book value of total assets.
Copyright © 2009 Pearson Prentice Hall. All rights reserved A second method uses the market values of the firm’s debt and equity. To find the market value proportion of debt, simply multiply the price of the firm’s bonds by the number outstanding. This is equal to the total market value of the firm’s debt. Next, perform the same computation for the firm’s equity by multiplying the price per share by the total number of shares outstanding. WACC = r a = w i r i + w p r p + w s r r or n The Weighted Average Cost of Capital Capital Structure Weights
Copyright © 2009 Pearson Prentice Hall. All rights reserved WACC = r a = w i r i + w p r p + w s r r or n The Weighted Average Cost of Capital Capital Structure Weights Finally, add together the total market value of the firm’s equity to the total market value of the firm’s debt. This yields the total market value of the firm’s assets. To estimate the market value weights, simply dividend the market value of either debt or equity by the market value of the firm’s assets.
Copyright © 2009 Pearson Prentice Hall. All rights reserved WACC = r a = w i r i + w p r p + w s r r or n The Weighted Average Cost of Capital Capital Structure Weights For example, assume the market value of the firm’s debt is $40 million, the market value of the firm’s preferred stock is $10 million, and the market value of the firm’s equity is $50 million. Dividing each component by the total of $100 million gives us market value weights of 40% debt, 10% preferred, and 50% common.

All rights reserved WACC = r a = w i r i + w p r p + w s r r or n The Weighted Average Cost of Capital Capital Structure Weights Using the costs previously calculated along with the market value weights, we may calculate the weighted average cost of capital as follows: WACC =.40(5.67%) +.10(9.62%) +.50(15.8%) = 11.13% This assumes the firm has sufficient retained earnings to fund any anticipated investment projects.
Copyright © 2009 Pearson Prentice Hall. All rights reserved The Marginal Cost & Investment Decisions The Weighted Marginal Cost of Capital (WMCC) –The WACC typically increases as the volume of new capital raised within a given period increases. –This is true because companies need to raise the return to investors in order to entice them to invest to compensate them for the increased risk introduced by larger volumes of capital raised. –In addition, the cost will eventually increase when the firm runs out of cheaper retained equity and is forced to raise new, more expensive equity capital.
Copyright © 2009 Pearson Prentice Hall. All rights reserved Finding the break points in the WMCC schedule will allow us to determine at what level of new financing the WACC will increase due to the factors listed above.

The Weighted Marginal Cost of Capital (WMCC) –Finding Break Points
Copyright © 2009 Pearson Prentice Hall. All rights reserved The Marginal Cost & Investment Decisions (cont.) The Weighted Marginal Cost of Capital (WMCC) –Finding Break Points Assume that in the example we have been using that the firm has $2 million of retained earnings available. When it is exhausted, the firm must issue new (more expensive) equity. Furthermore, the company believes it can raise $1 million of cheap debt after which it will cost 7% (after-tax) to raise additional debt. Given this information, the firm can determine its break points as follows:

The Weighted Marginal Cost of Capital (WMCC) –Finding Break Points BP equity =$2,000,000/.50 = $4,000,000 BP debt =$1,000,000/.40 = $2,500,000 This implies that the firm can fund up to $4 million of new investment before it is forced to issue new equity and $2.5 million of new investment before it is forced to raise more expensive debt. Given this information, we may calculate the WMCC as follows:
